Plastic Debris Found on One of World's Most Inaccessible Sites
It's becoming clear that plastic pollution is everywhere, even at the northernmost tip of the planet.
Scientists have recently found chunks of polystyrene on ice floes in the Central Arctic Ocean, about 1,000 miles from the north pole—an area that could not be accessed before due to sea ice, the Guardian reports.
"Vessels can now access and exploit a new, unexplored and vulnerable ocean region on the planet," an expedition blog post states, noting that approximately 1 million square kilometers of the Central Arctic Ocean is likely to have been ice-free this summer.
"For the 25 years I have been exploring the Arctic I have never seen such large and very visible items of rubbish," Hadow told the Guardian. "The blocks of polystyrene were just sitting on top of the ice."
These non-biodegradable items can break down into tiny pieces or microplastics and can get ingested by marine animals and enter the larger food chain. The area is home to polar bears, whales, seals, fish, seabirds and other species that are unique to the ecosystem.
"Finding pieces of rubbish like this is a worrying sign that melting ice may be allowing high levels of pollution to drift into these areas," marine biologist Tim Gordon of Exeter University in the U.K., who heads the research team, explained to the Guardian. "This is potentially very dangerous for the Arctic's wildlife."
"The Arctic Ocean's wildlife used to be protected by a layer of sea ice all year round," Gordon said. "Now that is melting away, this environment will be exposed to commercial fishing, shipping, and industry for the first time in history. We need to seriously consider how best to protect the Arctic's animals from these new threats."
At the same time, Ceri Lewis from the University of Exeter noted that Arctic thawing could also unlock massive amounts of frozen plastic.
"Many rivers that are often a source of plastic pollution lead into the Arctic Ocean, but plastic pollution has been literally trapped into the ice," Lewis said. "Now the ice is melting we believe microplastics are being released into the Arctic."
Scientists have shown that up to 12 million tonnes of plastic is entering our oceans every year—that's a rubbish truck full every minute.

The First Step in Managing Plastic Waste Is Measuring It – Here’s How We Did It for One Caribbean Country

To celebrate the 50th birthday of one of America's most important environmental laws, President Trump has decided to make a mockery out of it.
In 2018, there were about 5 million electric cars on the road globally. It sounds like a large number, but with well over a billion cars worldwide, electric vehicles are still only a small percentage.
